货币政策是调节汇率的重要手段。中央银行通过调整基准利率、公开市场操作等方式影响货币供应量和 市场利率水平。若中央银行提高利率，国内资产的收益率上升，会吸引国际资本流入以获取更高回报， 从而增加对本币的需求，促使本币升值；若降低利率，则可能导致资本外流，本币汇率走弱。此外，量 化宽松或紧缩政策也会通过影响货币供应总量，间接作用于汇率波动，调节市场的流动性状况。 国际收支状况对汇率有着直接影响。国际收支包括贸易收支和资本收支两部分。若一国贸易顺差（出口 大于进口），意味着外国需要更多本币来支付进口商品，本币需求增加，汇率上升；反之，贸易逆差会 导致本币供过于求，汇率下跌。资本账户方面，外国直接投资、证券投资等资本流入会增加本币需求， 推动汇率升值；资本外流则会对本币汇率产生贬值压力，二者共同构成了国际收支对汇率的影响逻辑。 通货膨胀水平的差异是影响汇率的长期因素。货币的购买力与通货膨胀率密切相关，若一国通货膨胀率 高于其他国家，其货币的实际购买力会下降，相对价值降低，导致本币汇率贬值；若通货膨胀率低于其 他国家，货币购买力更强，本币汇率更易升值。这一机制符合购买力平价理论的核心逻辑，是汇率长期 变动的重要参考依据 ...

Economic Fundamentals - Economic growth reflected by GDP growth rate influences currency demand and exchange rates, with stable growth attracting international capital and pushing exchange rates up, while slow growth or recession exerts depreciation pressure [1] - Inflation rates affect purchasing power; higher inflation compared to other countries leads to decreased confidence in the currency, resulting in downward pressure on exchange rates [1] - Interest rates are closely linked to exchange rates; higher interest rates attract capital inflow, increasing currency demand and supporting exchange rate appreciation, while lower rates can lead to capital outflow and suppress exchange rate performance [1] Monetary Policy - Central banks use monetary policy as a tool to regulate exchange rates, with the direction and intensity of policy having a direct impact [1] - The revised Foreign Exchange Management Regulations in 2025 enhance the macro-prudential management system, allowing the central bank to stabilize exchange rates through foreign exchange reserves and market operations [1] - Tight monetary policy can enhance currency attractiveness and promote appreciation, while loose policy increases money supply and lowers interest rates, leading to depreciation expectations [1] International Balance of Payments - The balance of payments, particularly the current account, reflects a country's external economic balance; a persistent surplus indicates higher demand for the currency, leading to a strong exchange rate, while a deficit exerts depreciation pressure [2] - Capital and financial accounts show cross-border capital flows; sustained net inflows increase demand for the currency, supporting exchange rate strength, while outflows create pressure [2] Geopolitical Factors - Geopolitical stability is crucial for attracting international capital; political turmoil or increased policy uncertainty can lead to capital outflow and currency depreciation [2] - Sudden events like geopolitical conflicts or natural disasters can trigger market risk aversion, causing investors to shift to traditional safe-haven currencies, leading to short-term appreciation of those currencies and depreciation of affected currencies [2] Market Sentiment and Speculation - Market sentiment and speculative behavior significantly influence short-term exchange rate fluctuations; expectations of currency appreciation can lead to buying pressure, while depreciation expectations can trigger sell-offs [2] - Large-scale speculative trading can amplify short-term volatility, especially in high liquidity conditions [2]
